miniVES is TCP/IP based scalable Public Address & Voice Alarm (PA/VA) unit suitable for multi-purpose architectures.
As a stand-alone unit miniVES is cost efficient and powerful PA/VA for small buildings like supermarket, hotel or school with basic features like voice evacuation, paging or back ground music.
Thanks to distributed network architecture, miniVES can be applied in variety of network applications e.g. transportation (railway, metro), hospital/university campuses, high rise building, industrial parks etc.
In order to provide highest safety and reliability of the system miniVES is designed as decentralized network concept what eliminates single point of system failure. That means if one part of the system fails, the rest will continue operating normally without any interruption.
Devices from miniVES series are Voice Alarm compact control units containing all components within one housing, which meet all the requirements of EN 54-16 and EN 54-4 (certificate of constancy of performace 1438-CPR-0527).
Control unit of miniVES is equipped with two independent class D amplifiers with a power of 160 W or 320 W, which distribute 100 V signals to 4 or 8 speaker lines depending on the type. The system also ensures operation of a backup amplifier for the evacuation signal.
miniVES is a complete VA system in which advanced energy saving mechanisms are implemented. miniVES control unit is equipped with an integrated battery charger, power supply system which meets the requirements of EN 54-4 and a dedicated shelf for batteries.
miniVES is designed as a Plug & Play unit –default setup enables operation after installation on the wall in basic configuration – just after connection of loudspeaker lines and installation of batteries in the housing. The factory configuration can be also easily modified according the building and evacuation scenarios.
PUBLIC ADDRESS SYSTEM IN STORES / SUPERMARKETS
Communication between microphones and PA/VA control unit is conducted via ETHERNET protocol – possibility of using typical SWITCHES to which microphone cables and then, a single cable are connected to miniVES control unit.
Zone microphone in the office section:
- it is a control unit of the PA system – it enables selection of a zone, activation and deactivation of sound sources or adjustment of sound level.
Zone microphone at the cash desk:
- transmission of verbal alerts;
- freely programmable buttons – activation of a button may result in a transmission of the alert that was already recorded in the system control unit, e.g. calling the store manager, noticing the customers of free cash desk, etc.
Built-in audio input in the control system enables a connection of external devices – transmission of background music of advertisements within the store.
PUBLIC ADDRESS SYSTEM IN TRANSPORT / RAILWAY / SUBWAY STATIONS
Equipping miniVES control unit with a communication card enables connection of multiple stations, separated from each other by several kilometers, into one system. It is possible to use the existing, logically-separated network infrastructure (VLAN) thanks to the communication between devices via ETHERNET.
Zone microphone at each station enables a transmission of verbal alerts or activation of the automatic alerts from system’s memory not only within the station but also to any speaker zone/s of the whole system, in order to inform the passengers awaiting a train about, for example, changes in traffic scheme or about any danger in the building.
Built-in audio inputs in every control unit and microphone enable a connection of external system signals and alerts coming from a primary, external information systems.
Built-in alert buffering function enables recording of low-priority information that are sent to the speaker lines occupied by primary sources and they are played automatically when the zones are free.
INDUSTRIAL FACILITY – NETWORK AUDIO COMMUNICATION SYSTEM
Equipping miniVES control units with communication cards enables connection of multiple industrial facilities into one system. Network cabling between control units made in the form of a fibre loop ensures that any damage of the cabling appearing in any place has no effect on the correct operation of the system.
Microphones located in the main building enable a transmission of verbal and/or automatic alerts to the selected speaker zones in all buildings.
Fireman’s microphone is a top-priority device, providing transmission of the alerts on threats to the people within all or selected buildings.
In case of fire emergency, receipt of control signals from Fire Alarm System or manual activation from the fireman’s microphone, the system sends alerts from the memory located in every miniVES control unit. Single devices operate as autonomous systems, ensuring continuous airing of the alerts on any threats, while total loss of the connection in a part of the systems takes place.
Speaker lines, within open areas, are connected to the central devices with certified surge arresters which ensure safety of devices in case of surges in speaker lines due to lightning discharge.
